You'd have to drink the ink.
Sharpie markers typically contain about 75-85% solvent, such as ethanol or isopropanol, which helps the ink flow smoothly and dry quickly. The solvent evaporates as the ink dries, leaving behind the pigments that create the permanent markers' color.

Sharpie markers have a pH level that ranges from approximately 6.5 to 7.5, making them slightly acidic to neutral.
You should not get ink poisoning if you put the ink just under the skin with the needle like some people do for home tattooing. But if you place the needle over a vein or major artery (such as you were tattooing on your wrist) you can get ink poisoning. Be very careful with what you do and always throughly think ahead.
Writing on your wrist with a sharpie can cause skin irritation or an allergic reaction for some individuals, especially if done repeatedly. Ink poisoning is generally not a concern unless the ink is ingested or absorbed in large quantities through broken skin. It is important to avoid writing on your skin with sharpies or other markers as a safety precaution.
Sharpie is known to be a long lasting marker for artists and students. The ink is always fresh and the writing is completely black in color.
